Depending on where you go, either one takes around the same amount of time. WGU, hertz, BSN is around 2.5 years. That last half year, you can extern at a hospital, they'll more than likely hire you afterwards when you've finished and tested. An ADN is 2. Speaking as someone that went older, was a SAHM, while you are in the groove of being a student just finish. You are not going to want to back. It's very tedious. If community college is more in your budget, start with ADN. Do not go into crazy debt for school. Hospitals are leaning towards BSN but a lot will still hire ADN with an agreement that you'll finish in 3-5 yrs. If your child isn't young, look into travel nursing. My cousin got her ADN from ivy tech community college and works at Northwestern, one of the top 10 in the US.
I know a lot of nurses use WGU for RN-BSN because you can finish in 6 months. I think Florida has one of the cheapest Universities for Nursing...... lucky dog.
I went to Purdue, I don't recommend it, the amount it cost is absolutely ridiculous. Wish you the best on your journey.
